[Diagnosis and treatment strategies for fatty liver when obesity coexists with alcohol consumption].

Non-alcoholic fatty liver disease and alcohol (ethanol)-related liver disease is a global epidemic of chronic liver disease and the main cause of fatty liver. Non-alcoholic fatty liver patients sometimes ingest different types of alcohol. Therefore, when obesity coexist with alcohol consumption, it is more difficult to diagnose the cause of fatty liver. The amount of alcohol consumption and alcohol drinking pattern and chronic liver injury, type 2 diabetes mellitus, cardiovascular disease and other metabolic-related diseases may have J-type correlation; that is to say, a light to moderate amount of alcohol consumption may bring certain benefits to the above diseases, but excessive alcohol consumption may promote the development of obesity, aggravate liver disease, metabolic abnormalities, and increase the risk of tumors. Screening for metabolic-related disease risk should be considered in addition to the assessment of changing liver lesions when obesity coexists with alcohol consumption. Changing bad living habits, losing weight and abstaining from alcohol are still the basis of treating fatty liver and metabolic disorders. Carefully selecting patients and communicating with them about the risk and benefit of drugs are important indicators of drug therapy. Patients with end-stage liver disease can be considered for liver transplantation and postoperative lifestyle improvement should be emphasized.
